Every commercial juicer gets a score from 0 to 100% built from up to six factors, which maps onto the 5-point rating shown on the site (a 0% score would be 1.5 stars; a perfect score, 5). Each factor is scored against fixed reference points, not against the other products in the list, so adding a new model never moves another model’s rating. Juicers are grouped by type: manual press, electric citrus, automatic citrus and juice extractors.
| Factor | Measures | Weight |
|---|---|---|
| Value | checked price, against others of its type | 25% |
| Output | published juice or fruit output rate | 25% |
| Power | motor rating | 15% |
| Feed size | feed chute or largest whole fruit taken | 10% |
| Sanitation | NSF, ETL Sanitation or UL Sanitation listing | 15% |
| Warranty | parts and labor warranty length | 10% |
Not every factor applies to every type. A factor that doesn’t apply is left out and the remaining weights are scaled up to the same total:
- Manual presses are scored on value, sanitation and warranty, since they have no motor and no rated output.
- Electric citrus juicers are scored on everything except feed size, since a reamer takes a fruit half of any size.
- Automatic citrus juicers and juice extractors are scored on all six.
Where the numbers come from
Output rates, motor ratings, feed sizes, sanitation listings, electrical ratings and warranties come from the maker’s or distributor’s specification sheet, or from the maker’s own copy on a retail listing where no spec sheet is published. Prices are checked at the stores each page links to, and the lowest price is used.
The factors
Value is the current price on a log scale, so halving the price always counts the same, with reference points set for each type: $400 scores zero and $100 full marks for a manual press, $1,200 and $200 for an electric citrus juicer, $10,000 and $500 for an automatic citrus juicer, and $5,000 and $400 for a juice extractor.
Output is the maker’s published production rate. For an electric citrus juicer, 60 oranges an hour scores zero and 300 full marks; where only liters of juice per hour are published, 10 L scores zero and 60 L full marks. For an automatic citrus juicer, 10 fruits a minute scores zero and 40 full marks (the top of a published range is used). For a juice extractor, 60 L of juice an hour scores zero and 160 L full marks.
Power is the motor rating. For citrus machines, 100 W scores zero and 400 W full marks; for juice extractors, 300 W scores zero and 1,300 W full marks. Motors rated only in horsepower are converted at 746 W per hp.
Feed size is the feed chute diameter on a juice extractor, where 2 in scores zero and 3.25 in (wide enough for a whole apple) full marks, and the largest whole fruit an automatic citrus juicer takes, where 70 mm scores zero and 90 mm full marks.
Sanitation is full marks for an NSF, ETL Sanitation or UL Sanitation listing, which most health inspectors look for in a licensed kitchen, and zero without one. A UL, ETL or TUV electrical mark alone doesn’t count.
Warranty is the maker’s parts and labor warranty: 1 year scores zero and 3 years full marks. A longer motor-only warranty is shown on the product page but not scored.
What isn’t scored
Continuous-duty ratings, motor speed, reamer count, lever force, pulp ejection, pulp bin size, feeder capacity, voltage and amperage, weight and release date are listed but not scored.
Missing data
If a figure isn’t published, that factor gets the neutral middle score (50) and the product page marks it as estimated. Three factors are exceptions. Output is the figure that most separates one juicer from another, so a juicer with no published output rate scores zero for it rather than a neutral middle, which keeps thin listings from ranking above well-documented machines. A juicer with no published sanitation listing is scored as unlisted, and a maker that doesn’t publish a warranty gets no warranty counted. Each of those factors scores zero and is marked estimated.
Ties and discontinued models
Products are ranked by score within each group. Discontinued models stay listed but rank below every current model and can be hidden with the “Hide discontinued” filter.
